objective(s):to optimize the extraction method using response surface methodology, extract the phenolic compounds, and identify the antioxidant and biological properties of stachys parviflora l.  extracts. materials and methods: maceration and ultrasound-assisted extraction (uae) (4, 7, 10 min treatment time, 40, 70, 100 % high-intensity and 60, 80, 100 % (v v-1) methanol purity) were applied t...

Sugar apple (Annona squamosa L.) is a popular tropical fruit and its peel is a municipal waste. An ultrasound-assisted extraction method was developed for the recovery of natural antioxidants from sugar apple peel. Central composite design was used to optimize solvent concentration (13.2%-46.8%), ultrasonic time (33.2-66.8 min), and temperature (43.2-76.8 °C) for the recovery of natural antioxi...

A simple HPLC-UV method has been developed and validated for the quantification of ellagic acid (EA) in ethanol extracts of Eugenia uniflora L. (Myrtaceae) leaves. The ultrasound-assisted extraction (UAE) optimization was performed using a Box Behnken design (33) combined with response surface methodology to study the effects of the ethanol concentration (%, w/w), extraction time (minutes), and...

Bioactive ingredients can be extracted from surplus soft fruits to add value them as a fortification ingredient in many new products. Ultrasound-assisted extraction and spray drying have been heavily studied the past, with evidence suggest positive uptake of these by food industry. In this paper, strawberries, raspberries blackberries were examined using distilled water ‘green’ method assisted ...

Plant extraction has existed for a long time and is still of interest. Due to technological improvements, it now possible obtain extracts with higher yields. While global yield major parameter because assesses the performance, can be interest focus on particular compounds (specific metabolites) enrich sample avoid unwanted ones, instance primary metabolites (carbohydrates, triacylglycerols). Th...

Quercetin is a biological flavonoid, which can be found in red kidney bean at high concentration. In this study, a comparison was conducted between traditional and modern extraction methods. Sequential microwave-assisted extraction was used for isolation of quercetin from red kidney bean. The effect of several factors such as particle size of grinded kidney bean, extraction solvent, microwave p...

Betalains are water-soluble pigments that have exhibited important pharmacological properties such as antioxidant, anticancer, antilipidemic and antimicrobial activity. These compounds been isolated in numerous purple plants or fruits, is the case of wild species under Opuntia genus. The fruits these often disregarded because their small size well frequent presence prickles. Based on this, this...

Focused open-vessel microwave-assisted extraction (FOV-MAE), closed-vessel microwave-assisted extraction (CV-MAE), and accelerated solvent extraction (ASE) were used for extraction before determination of organochlorine compounds (polychlorinated biphenyls, DDT, toxaphene, chlordane, hexachlorobenzene, hexachlorocyclohexanes, and dieldrin) in cod liver and fish fillets. Wet samples were extract...

Carotenoids are pigments found in various types of fruits and vegetables that provide yellow, orange, red colors. This study aimed to extract yellow pumpkin skin using edible oil solvents. The extraction process was carried out ultrasound-assisted (UAE) method with virgin coconut (VCO) palm kernel (PKO). Yellow peel powder sizes 40 mesh 100 were extracted variations time (30 minutes, 60 90 minu...
